  2. Beam splitter - Wikipedia

    en.wikipedia.org/wiki/Beam_splitter

    A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.

  3. Pellicle mirror - Wikipedia

    en.wikipedia.org/wiki/Pellicle_mirror

    Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters. [1] The name pellicle is a diminutive of pellis, a skin or film.

  4. Mach–Zehnder interferometer - Wikipedia

    en.wikipedia.org/wiki/Mach–Zehnder_interferometer

    By appropriately adjusting the mirrors and beam splitters, the fringes can be localized in any desired plane. The Mach–Zehnder check interferometer is a highly configurable instrument. In contrast to the well-known Michelson interferometer , each of the well-separated light paths is traversed only once.

  5. Self-mixing interferometry - Wikipedia

    en.wikipedia.org/wiki/Self-mixing_interferometry

    Set-up of a self-mixing interferometer with laser diode and monitor photodiode. Self-mixing or back-injection laser interferometry is an interferometric technique in which a part of the light reflected by a vibrating target is reflected into the laser cavity, causing a modulation both in amplitude and in frequency of the emitted optical beam.

    en.wikipedia.org/wiki/Reflector_sight

    The reticle image in this sight is produced by an optical collimator bounced off a beam splitter. The dot remains on the target even though the viewer's head is moved side to side A reflector sight or reflex sight is an optical sight that allows the user to look through a partially reflecting glass element and see an illuminated projection of ...

  9. Jones calculus - Wikipedia

    en.wikipedia.org/wiki/Jones_calculus

    The Jones matrices are operators that act on the Jones vectors defined above. These matrices are implemented by various optical elements such as lenses, beam splitters, mirrors, etc. Each matrix represents projection onto a one-dimensional complex subspace of the Jones vectors. The following table gives examples of Jones matrices for polarizers:
